Title: Photometric apparatus
IPC: G01J1/42
Filed: 1969-07-31
Abstract: 1282587 Exposure meter AGFA-GEVAERT AG 31 July 1969 [31 July 1968 and 30 Aug 1968] 38449/69 Heading G1P [Also in Division G2] A photo-metric apparatus acting as an exposure meter comprises, an internal comparison source 10 Fig.4 and a brightness indicator including one or more interference mirrors 8, 9 which are arranged such that light from source 10 is incident on one face of the mirror and light from an external source 11 is incident only on the other face thereof to enable an intensity comparison to be made by an observer located adjacent the comparison source. The colour seen by the observer is made up of light transmitted from the external source and light reflected from the comparison source and at balance if the mirrors are non-absorbing white light is observed. The interference mirror(s) include an interference layer which either absorbs or does not absorb visible light. A colour filter may be included in the mirror, preferably as a support for the layer which then gives definite colours when referenced with the comparison source. To increase the sensitivity multiple interference layers may be used. In a system applicable to a camera view-finder Fig. 6 (not shown) a reference colour is always visible as a ring about an aperture, this being achieved by the use of stops (29, 30) the latter having a fully reflective inner face (30a) to give a better contrast at balance with the green, yellow or red light which appears at the centre of the ring according to outside light conductors. Sensitivity may also be improved by placing a grey filter behind the mirror(s) on the side remote from the observer. As shown, applied to a camera Fig.10 two adjacent interference mirrors 66, 67 are provided having opposite reflectance/transmittance characteristics with a variable intensity comparison source 70 which is controlled by the resistances 81, 75 linked to the setting of the aperture and shutter speed. The resistances 81, 75 are adjusted according to the direction of the arrows 68, 69 provided on a mask over the mirrors 66, 67, illuminated by comparison source 70, until a colour change occurs whence suitable conditions for taking a correctly exposed photograph will result. In order to ascertain whether correct exposure is possible under extremes of external illumination, the switch 74 is closed on to 74b and 80, 86 are closed, switch 87 then provides access to two circuits containing fixed resistances 88, 89 which correspond to the minimum and maximum output from the internal light source, the external brightness is then compared with these.

Abstract: 1356226 Spot-type disc brakes; actuators and wear-adjusting HONDA GIKEN KOGYO KK 25 Aug 1972 [28 Aug 1971] 39863/72 Heading F2E A disc brake has a caliper member 3, Fig. 1, extending over a brake disc 2 and carrying a first pad 7 fast with the caliper member 3, and a second pad 8 movable with respect to the caliper member 3; the second pad 8 is connected to an advancing member (e.g. 11, 12) which is moved by actuation of an operating member (e.g. 14, Figs. 1 and 2), and which is connected through a one-way clutch (e.g. 26, 27, Fig. 3) to one end of a return spring 23, this return spring being connected at this one end to the one-way clutch and at the other end to the operating member (e.g. 14, Fig. 3). In the spot-type disc brake shown, caliper 3 is connected by an arm 5 to a pivot 6 on a vehicle body, Fig. 2. Pad 7 is secured to the caliper, while pad 8 is slidable in a guide tube 9 integral with the caliper, Fig. 1. A pressure plate 13, Figs. 1 and 2, is prevented from rotating by engagement of a claw member 17 on it with a groove 18, Fig. 2, and a pin 19 projecting from the plate prevents rotation of pad 8. Tube 12, to which pressure plate 13 is secured, is thus also prevented from rotating, while screw 11, engaged within it and having rotatable engagement at 10 with pad 8, is rotatable. In operation, when the operating lever 14, loosely mounted on tube 12, is rotated clockwise (Fig. 2) by wire 21, a ball-and-ramp arrangement 15, 16, forces plate 13, tube 12, screw 11 and pad 8 to the left, Fig. 1, while a ratchet wheel 27 (forming part of a one-way clutch 24) is forced to follow by a spring 31. The helical return spring 23, linking lever 14 and a pawl plate 26, Figs. 3 and 4, is compressed by tube flange 29 acting through balls 30 on pawl plate 26, and in normal operation the spring 23 causes pawls 25 to follow the rotational movement of lever 14 and drive ratchet wheel 27 and thus, by rectangular section shaft 28, screw 11 in tube 12, Fig. 1. If rotation is excessive due to wear, pawls 25 each jump a tooth on brake release. When the brake is in the applied condition, the friction between tube 12 and screw 11 is such that further rotation of lever 14 serves only to twist spring 23, avoiding unnecessary excess adjustment. Pad 7 is applied by reaction through thrust bearing 22. The at-rest position may also be adjusted directly by setting screw 11 in tube 12.

Abstract: 1,086,911. Road vehicle spring suspension. J. J. M. J. GERIN. Oct. 1, 1964 [Oct. 3, 1963], No. 40029/64. Heading B7D. In a variable-height suspension system for a vehicle, each wheel is independently suspended by resilient means positioned by a power control arrangement operable by the driver to effect simultaneous adjustment of the position of all the wheels or of those on opposite sides of the vehicle. Each front wheel, Fig. 4, is carried by an arm 4 -pivoted on a transverse shaft 5 in a casing 7 which is steerable about pivots 8 by steering mechanism connected to a ball-joint 10. The arm 4 is connected to a fork 12 on the rod 13 of a piston 14 abutting a spring 19 in a cylinder 15 which is pivotally connected to a lever 18 adjustable about the pivot shaft 5 by means of a nut 21 engaging a threaded shaft 22 driven by an electric motor 24, or by pneumatic, hydraulic or other electrical or mechanical means. In Fig. 15 (not shown) additional springs (43, 44) in the cylinder (15) abut the piston (14) in sequence to provide progressive springing -and movement of the piston is damped by filling the cylinder with oil and providing valve-controlled openings (45) in the piston. Each rear wheel, Fig. 8, is mounted on an arm 4 whichis secured to a shaft 5 journalled in support 27 on the vehicle body and carries a cam plate 32 co-operating with a pin 31 on a stirrup 29 connected to the rod 13 of a piston 14 abutting a spring 19 in a cylinder 15 carried by a member- 28 pivotable about the shaft 5 by an hydraulic jack 35. In Fig. 10 (not shown) an hydropneumatic spring (36) replacing the cylinder (15) is actuated by an arm (40) on the shaft (5) through a rod (38). In Fig. 16 (not shown) the cylinder (15) is connected to the vehicle body by a pivotal connection (49) spaced from and parallel to the shaft (5). The position of the wheels is controlled by two manually-operated contacts arranged on opposite sides of the steering wheel such that actuatipn of either contact alone raises that side of the vehicle and lowers the other, whereas actuation of both contacts selects the highest body position. The position of the wheels may also be controlled automatically to incline the body inwardly during a turn by a pendulum or weights responsive to centrifugal force.
